File renameTo not working

[jin sun]

This is frustrating, I had it working a while ago but now it isn't working. The renameTo is returning false but I deleted the file with the same name that I'm trying to rename and closed the output and input streams. I also checked the permissions. Anyone have a clue what I'm doing wrong? Thanks in advance.

 public void mrxwsort(String concept){
    try{
      BufferedReader in = new BufferedReader(new FileReader("MRXW_ENG.rrf"));
      String str1,a,b;
      String[] token1;
      BufferedWriter fr = new BufferedWriter( new FileWriter("TEST.RRF", false));
      String testfile = "TEST.RFF";
      String mrfile = "MRXW_ENG.rrf";
      File test = new File(testfile);
      File mr = new File(mrfile);
 
      str1 = in.readLine();
 
      int end = 0;
 
      if (str1 == null){
          fr.write("ENG|" + concept.toLowerCase() + "|" + cui + "|" + lui + "|" +
                    sui + "|\r\n");
           fr.close();
      }
      else{
        token1 = str1.split("[|]");
        while ( (str1 != null) && (end == 0)) {
          if (concept.compareTo(token1[1]) > 0) {
            if (baseWordChecker(concept, token1[1], str1, fr) == 0) {
              fr.write(str1 + "\r\n");
              str1 = in.readLine();
              if (str1 != null)
                token1 = str1.split("[|]");
            }
            else {
              end = 1;
            }
          }
          else {
            if (baseWordChecker(concept, token1[1], str1, fr) == 1) {
              str1 = in.readLine();
              if (str1 != null)
                token1 = str1.split("[|]");
            }
            else
              end = 1;
          }
        }
 
        fr.write("ENG|" + concept.toLowerCase() + "|" + cui + "|" + lui + "|" +
                 sui + "|\r\n");
        if (str1 != null)
          fr.write(str1 + "\r\n");
 
        str1 = in.readLine();
        while (str1 != null) {
          fr.write(str1 + "\r\n");
          str1 = in.readLine();
        }
        in.close();
        fr.close();
      }
      
      a = ""+mr.delete();
      b = ""+test.renameTo(mr); //mr is deleted and returns true
 
      System.out.println(a);
      System.out.println(b);
    }
    catch (IOException ioe){
      try{
        BufferedWriter fr = new BufferedWriter( new FileWriter("TEST.RRF", false));
        fr.write("ENG|" + concept.toLowerCase() + "|" + cui + "|" + lui + "|" +
                 sui + "|\r\n");
        fr.close();
 
        BufferedReader inn = new BufferedReader(new FileReader("TEST.RRF"));
        String strr;
        BufferedWriter frr = new BufferedWriter( new FileWriter("MRXW_ENG.RRF", false));
 
        while ((strr = inn.readLine()) != null){
          frr.write(strr+"\r\n");
        }
        inn.close();
        frr.close();
 
      }
      catch(IOException e){
        e.printStackTrace();
      }
    }
  }

Hi.

A couple of months ago a friend have asked for my help in a similar situation. The renameTo was not working and the problem was on the file path as he was trying to rename with only the file name. Try to include the complete path for the file, for example,

 
String testfile = "c:\\TEST.RFF";
String mrfile = "c:\\MRXW_ENG.rrf";
File test = new File(testfile);
File mr = new File(mrfile);
